STEAM-BOILER -FEEBE teenies.

Application led November l,

To all whom it may concern:

lie it known thatwe, BARNEY .Zinnen and y WILLIAM il. "HART citizens of the United declare'the following exact description ot the invention, such as will enable others skilled in the art to which it appertains to malte and use the same.

Our invention relates to improvements inv ifeeders for steam boilers and more particularly to those which heat the feed water before injecting the same into the boiler. Y

rthe principal object oi: our invention 1s to provide a simple, inexpensive and. easily 1 installed apparatus which may Well be used tion ot our invention;

' srnolie box 2, whereas a upon locomotives, provision being made so that throwing ot the entire teeder out of use is not necessary in case of injury to certain parts thereot.

With the 'foregoing general object' in view, the invention resides in the novel fea-r tures ot construction and unique,.combina-l tions ct parts to be hereinafter tullyn described and claimed, the descriptive matter being supplemented. by the accompanying drawings which torni a part of this specification and in which:

Figure tive, partly in section, showing Fig. 2 is an end elevation partly in sec'- tion; and

Figs. 3, Il and 5 are diagrams showing the different courses which the teed water may be madeto. travel.

ln the drawings above briefly described, y

the numeral 1 designates a locomotive boiler, 2 the smoke box at the front end ot said boiler, 3 the cab at the rear end thereotl and 4 the smoke stack from said smoke box, all of these features being of Well lrnown construction.

An injector 5 is provided within the cab 3, said injector having the usual steam inlet 6, water inlet 7, and drain 8. A feed water pipe 9 leads from the injector 5 to multiple pipe heater 10 positioned in the return pipe ll leads 'from said heater and boiler 12, said return pipe including a checi@` valve 13 having a valyed drain 1li.

A. second injector l5 preferably identical Specification of Letters Patent.Y

'Supplying' is a side elevation of a locomo-l the apphcadischarges into the Patented dan. 22, i918.

with the injector 5 is provided, and a second feed Water pipe 16 leads from said second injector and by means of a three Way valve 17 is connected to the Jfeed water pipe 9, both of said feed Water pipes having check valves 18 between said three-Way valve and their respective injectors.

A second return pipe 19 discharges at 20'*v into the boiler and includes a check valve return pipe being connected to the return pipe 11 by a three-Way valve 22. A. by-pass pipe 23 connects the feed water pipe 9 with the second return pipe 19, said .by-pass pipe having a cut-od valve 24 and'said pipe9 having a similar valve 25 lbetween said icy-pass pipe and the heater 10. lAt the juncture ot the pipe 23 with the reta/rn pipe 19,4the latter is provided with .a

21, said second valved 'drain126.

By positioning the valve 17 as shown in Fig/3', ,the injector 15 may be Jused 'feed/ water to the pipe 9, or 1f thisl injector should become in any Way damaged,y the valve 1'4" may be turned to the position/01V Fig. 4,' so`that the injector 5 may be used. The Waterfrom the pipo 9 may be passedthrough the heater 10 as indicated by the larrows in Figs. 3 and 4, but if this heater should be burned out or otherwise damaged, valve 25 may be closed and 24: opened as indicated in Fig. 5. This will prevent the passage of water through the heater and although this Water will not. be heated, it will be injected into the boiler through the pipe 19. By proper manipulation of the three-Way `.valve 22. the water may be forced to traveleither through the pipe 19 as shownin Fig. 8, or through pipe 11 as indicated in Fig. 4. it will be underl stood that the valve 22 must be closed simultaneouslv with closing of valve 25, when the heater 10 isl to be thrown out of action.

kFrom` the foregoing, taken in connection with the accompanying drawings, it will be obvious that although our invention is of extremely simple and inexpensive nature, it will be highly eiiicient and-durable. For these reasons, the several details shown and described are preferably employed, but we, wish it understood that withinthc scope ot the invention as claimed. numerous minor an injector, feed Water pipe leading from said injector to said heater, a return pipe from said heater into the boiler, a. second.

injector, a second feed water pipe leading from said second injector, a three-way valve connecting said second feed water pipe with the first, a second return pipe discharging into the'boiler, a second three-way valve connecting said second return pipe with 'the first, 'a by-pass pipe leading from the first named feed Water pipe to one of said return pipes between said second three-Way valve and the delivery end of said. pipe, a valve for said by-puss pipe, and a valve for said first named feed water pipe between seid 15 by-pass pipe and said heater. In testimony whereof we have hereunto set -our hands in the presence of ,two scrbing witnesses. i
